* 'release-2.6.27' of git://git.kernel.org/pub/scm/linux/kernel/git/ak/linux-acpi-merge-2.6: (87 commits)
  Fix FADT parsing
  Add the ability to reset the machine using the RESET_REG in ACPI's FADT table.
  ACPI: use dev_printk when possible
  PNPACPI: add support for HP vendor-specific CCSR descriptors
  PNP: avoid legacy IDE IRQs
  PNP: convert resource options to single linked list
  ISAPNP: handle independent options following dependent ones
  PNP: remove extra 0x100 bit from option priority
  PNP: support optional IRQ resources
  PNP: rename pnp_register_*_resource() local variables
  PNPACPI: ignore _PRS interrupt numbers larger than PNP_IRQ_NR
  PNP: centralize resource option allocations
  PNP: remove redundant pnp_can_configure() check
  PNP: make resource assignment functions return 0 (success) or -EBUSY (failure)
  PNP: in debug resource dump, make empty list obvious
  PNP: improve resource assignment debug
  PNP: increase I/O port & memory option address sizes
  PNP: introduce pnp_irq_mask_t typedef
  PNP: make resource option structures private to PNP subsystem
  PNP: define PNP-specific IORESOURCE_IO_* flags alongside IRQ, DMA, MEM

None of these counters has an effect on the function
of the system, they are simply statistics.
Besides this, user can also write specific strings to these files
to enable/disable/clear ACPI interrupts in user space, which can be
used to debug some ACPI interrupt storm issues.
Note that only writting to VALID GPE/Fixed Event is allowed,
i.e. user can only change the status of runtime GPE and
Fixed Event with event handler installed.
Let's take power button fixed event for example, please kill acpid
and other user space applications so that the machine won't shutdown
when pressing the power button.

Compal FL90/IFL90
Compal FL91/IFL91
Compal FL92/JFL92
Compal FT00/IFT00
It adds support for Bluetooth, WLAN and LCD brightness control.
If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
config SONY_LAPTOP
tristate "Sony Laptop Extras"
depends on X86 && ACPI
